Can't control TDP in older Intel devices

[Rinzheim]

There's no TDP CONTROL in old intel devices like the GPD WIN 2

SMT and core parking works well, but you can't control GPU Frequency or TDP. In windows you can also control undervolt, would be great if added too.

There's also a m3-8100y version of the device, but it uses the same GPU so it should not make any difference.
